Abstract
A hydrocracking process is provided which process utilizes a sulfated solid catalyst comprising (1) oxide or hydroxide of Group III or Group IV element, e.g. zirconium, and (2) a first metal comprising a metal or combination of metals selected from the group consisting of platinum, palladium, nickel, platinum and rhenium, and platinum and tin. The catalyst may further comprise (3) a second metal selected from the group consisting of Group VIII elements, e.g. iron. One embodiment of the invention further comprises (4) a third metal selected from the group consisting of Group V, VI and VII elements, e.g. manganese.
Claims18
A process for hydrocracking a hydrocracking feedstock, which process comprises contacting said feedstock, in the presence of hydrogen, with a catalyst comprising a mixture of:
- (a) a sulfated support comprising oxide or hydroxide of Group III or Group IV elements;
- and
- (b) a first metal comprising a metal or mixture of metals selected from the group consisting of platinum;
- palladium;
- nickel;
- platinum and rhenium;
- and platinum and tin, and combinations there of;
- wherein said catalyst is prepared by the steps comprising:
- (1) calcining said sulfated support in a first calcination step;
- (2) introducing said first metal into said sulfated support;
- and
- (3) calcining said sulfated support and said first metal in a second calcination step;
- wherein said second calcination step is carried out at a lower temperature than said first calcination step.
